Abstract
The invention relates to a hydraulic power shaft hole separator. The hydraulic power shaft hole separator comprises a cylinder body, a piston, a return spring, a cylinder cover, a guide ring, a seal ring, a piston rod seal ring, a dust prevention seal ring, a double-thread sleeve and a cushion block. The cylinder body is connected with the cylinder cover through threads, and the piston and the cylinder body seal hydraulic oil through the seal ring, the piston rod seal ring and the guide ring; the dust prevention seal ring prevents dust from entering the cylinder body; the upper portion of the piston is sleeved with the return spring; the double-thread sleeve and the cushion block are connected to the bottom of the cylinder body in a matched mode, and the inner hole of the cushion block is in clearance fit with the double-thread sleeve. The hydraulic power shaft hole separator is applied to inner ring close fit disassembly of large bearings and has the advantages of being large in disassembly force, stable in speed, easy to operate and not prone to damaging related parts.
Description
Technical field
The present invention relates to a kind of hydraulic power axis hole separator.
Background technology
At present, both at home and abroad about the draw-off gear of bearing part is more, but ubiquity bearing aperture is less, the problem that pulling force is lower, and on large size bearing, general employing is manually beaten or the mode such as gas welding cutting, can cause certain destruction to relevant device.
Summary of the invention
The object of the invention is to the deficiency existed for prior art, a kind of hydraulic power axis hole separator is provided.This separator effectively can solve the dismounting that macro-axis holds class, ensures stable Output pressure, simple to operate, and efficiency is high can not destroy related components simultaneously.
For achieving the above object, the present invention adopts following technical proposals:
A kind of hydraulic power axis hole separator, comprises cylinder body, piston, restoring spring, cylinder cap, guide ring, sealing ring, piston rod packing circle, dust-proof seal ring, two thread bush, cushion block; Described cylinder block and cylinder cover is threaded connection, and described piston and cylinder are by sealing ring, piston rod packing circle, guide ring sealing fluid force feed; Described dust-proof seal ring blocks dust enters cylinder body; Described restoring spring is sleeved on described upper piston area; Described pair of thread bush and cushion block are connected in the bottom of cylinder body, endoporus and two thread bush matched in clearance of cushion block.
Described piston is nonstandard piston, and piston two ends have screwed hole to be respectively used to connect oil sources and two thread bush; Piston is having the passage of small-bore with oil sources junction, and leads to the other end of piston always; Be provided with the shaft shoulder at the interlude of piston, the shoulder end face of the shaft shoulder has concave ring groove and restoring spring to compress; Two grooves are had, for installing guide ring and sealing ring at shaft shoulder arc surface.
The present invention compared with prior art, has following apparent outstanding substantive distinguishing features and remarkable technological progress:
Hydraulic power axis hole separator of the present invention applies to the friction tight dismounting of inner ring of large size bearing class, has the power of tearing open large, and speed is steady, simple to operate, the advantage of survivable correlated parts.
Accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic power axis hole separator of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are described further.
As shown in Figure 1, a kind of hydraulic power axis hole separator, comprises cylinder body 1, piston 2, restoring spring 3, cylinder cap 4, guide ring 5, sealing ring 6, piston rod packing circle 7, dust-proof seal ring 8, two thread bush 9, cushion block 10; Described cylinder body 1 is threaded connection with cylinder cap 4, and described piston 2 and cylinder 1 are by sealing ring 6, piston rod packing circle 7, guide ring 5 sealing fluid force feed; Described dust-proof seal ring 8 blocks dust enters cylinder body 1; Described restoring spring 3 is sleeved on described piston 2 top; Described pair of thread bush 9 and cushion block 10 are connected in the bottom of cylinder body 1, endoporus and two thread bush 9 matched in clearance of cushion block 10.
Described piston 2 is nonstandard piston, and piston 2 two ends have screwed hole to be respectively used to connect oil sources and two thread bush 9; Piston 2 is having the passage of small-bore with oil sources junction, and leads to the other end of piston 2 always; Be provided with the shaft shoulder at the interlude of piston 2, the shoulder end face of the shaft shoulder has concave ring groove and restoring spring 3 to compress; Two grooves are had, for installing guide ring 5 and sealing ring 6 at shaft shoulder arc surface.
Operation principle of the present invention is as follows:
Before work, piston 2 compresses by restoring spring 3, and piston 2 keeps fitting with cylinder body 1; Two thread bush 9 is connected with the tool process screwed hole of piston 2, the supporting process face of cushion block 10 end face and cylinder body 1 is adjacent to simultaneously.Under duty, hydraulic oil is flowed into by the entrance of piston 2, flows out from other end outlet, piston 2 under the effect of oil pressure on move, and now piston 2 and axle keep connection status, thus axle can along with the inflow of hydraulic oil on move, the bearing be connected with axle departs from axle gradually under the effect of cushion block 10.
